The dynaflow pillar: the agent-orchestration engine and visual node builder that turns dynavec from a vector DB into a full, in-your-own-account agent framework. A graph/DAG runtime (nodes + edges, shared state, conditional routing, loops, retries, resumability), a typed node system, agent + model primitives, and a ReactFlow canvas where code ⇄ visual are two views of the same graph.

Tagline: Build & run. Status: to build (P1–P3, P5).

This epic tracks the child issues below; see the roadmap §5 (core modules) and §6 (visual builder).
